To all whom it may concern: I

Be it known that we, JACOB B. MERKEL and GEORGE J. CARnoLL, citizens ofthe United States of America, residing at Tam--- aqua, in the county ofSchuylkill and State of Pennsylvania, have invented newand' usefulImprovements in Film-Winding Mechanism for Moving-Picture Machines,

ofwhich the following is a specification.

This invention relates to film winding mechanism for motion picturemachines, and.

it has for'an'object to provide mechanism which can be operated toobviate the usual winding and rewinding of the film before projection ofthe picture means being employed whereby the ordinary film spools orreels can be used in the initial operation of the mechanism.

Another object of the invention is to emreceiving reel and arranging iton the magazine reelfrom which the film can be drawn from the center tothe said receiving reel.

In the drawings, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several viewsFigure 1 is a detail horizontal section taken on the line 44 of Fig. 1.Fig. 2 is a. side elevation of the top magazine. Fig. 3 is a front viewthereof. Fig. 4 is a side elevation of our improved mechanism showingthe same applied to a moving picture machine, the. closures for theupper and lower magazines being shown in their open positions and thefilm in place for 1QX l1lbition.

The moving picture machine which is illustrated at A in F 1 of thedrawings, may be of any well known approved con struction, but asillustrated, it is provided with the usual driven shaft 1 for the filmspool or reel 2 which is mounted in a lower magazine This magazine isprovided with a hinged closure 4. so that the operator can readily gainaccess to the interior thereof y when it is desired to remove the filmspool.

The said film spool is formedqof separahle sections 5 and 6 which areseparated from eachother by a hub 7 The top magazine 8 is of a designcon structed to accommodate our improved mechanism and it consistspreferably of an inclosure 9 which is provided with a hinged closure 10.The inclosure is formed to provide a circular base 11 on. which isrevolubly mounted a film-guiding tray 12, a centrally disposed verticalshaft 13 being mounted on the base for supporting a bearing member ltton which companion guide rollers 15 are mounted, the said'rollers beingdisposed at an acute angle with respect to the base of the tray 12 for apurpose to be hereinafter described. The'magazine is formed to provide'asubstantially rectangular portion 16 and on the bottom wall thereof apair of yieldingly mounted film-guiding rollers 17 are mounted, the saidrollers being movable relatively to and yieldingly engaged with eachother preferab'iy'by springs 18. The closure 1O of the magazine 9 justdescribed is provided with a suitable handle 19 and the front wall ofthe rectangular portion 16 of the magazine is provided with a springclasp 20 adapted to engage the closure 10 to hold the same in its closedposition. The

magazine is provided with a snaft 21 which supports the film spool ,orreel 22 in the initial operation of the machine so that the film can bearound from such reel to the receiving reel 2 in the bottom magazine.The top magazine is provided with a bracket plate/23 having apertures 2%for receiving the clamping bolts 25 on the frame of the moving picturemachine.

In the initial operation of the machine, assuming that the film has notbeen an wound from the reel 22 the front end of the film which of courseis ordinarily disposed outermost is operatively associated with themechanism of the moving picture machine and with the receivingspool orreel 2 so that when power is imparted to the shaft 1 of the lowermagazine the reel 2 will be revolved to wind the film from the reel 22onto the said reel 2. After the film has been.

shown as just described it will obviously i said reel 2 from-itsmagazine and separate 'the parts 6 and 7 from each other. We then removethe film entirely from this reel and substitute for the reel-the reel 22in the uppermost magazine, after which placing the film upon the lowerreel in the film-guiding tray 12 of the upper magazine. As the film inits present form is wound so that its front end is innermost of all theWound portion the. operator grasps the said innermost or front endportion -and threads it through the guide rollers 15 and then over theroller 17' at the'topof the portion 16 of the inclosure and then throughthe rollers 17, after which the film is of course operatively associatedwith the mechanism of the moving picture machine and such front end orterminal is then secured to the winding reel. After the film has beenwound in this manner it may be again removed from the lower magazine andplaced in the guiding tray 12 for immediate display. As stated, thefilmguiding rollers'15 are disposed at. an acute angletothe film-guidingtrayor support 12: The rollers 17 are disposed horizontally and receivethe film from the guide rollers 15 and 17 without twisting the film. toany great extent, thus obviating undue mutilation thereof.

We claim: I

1. Film-Winding mechanism for moving picture machines comprising anupper magazine, a lower magazine, a reel of separable elements removablyand revolubly mounted in thelower magazine, a reel support in theuppermagazine, and a second reel support in the upper magazine anddisposed at right angles to the first reel support therein for holdingthe film horizontally in coil form so that the film can be fed from itsinnermost wound portion to the reel in the lower magazine.

2. In film-windin mechanism, an upper magazine, .a revolu ly mountedfilm-supporting member located in the magazine and supporting the filmin coil form, a reel support located forwardly of the first support anddisposed at right angles to the axis of the support, a second magazine,and a winding reel in the second magazine and having its axis parallelto the second named'support in the. first named magazine and at rightangles to the first named magazine.

3. In a moving picture machine, the combination of a reel supportingbox, means ar-
